Summary: The muscle-sparing thoracotomy offers several benefits over the traditional posterolateral thoracotomy approach for surgically accessing the chest cavity. Some of the potential advantages of preserving the latissimus dorsi and serratus anterior muscles include both functional benefits and potential use of these muscles for future flap reconstruction. Nevertheless, the muscle-sparing thoracotomy technique has traditionally been described with a wide exposure and, as a result, a theoretically higher risk of seroma and hematoma formation due to the increased dead space. The authors propose a new approach to muscle-sparing thoracotomy to avoid the disadvantages of each technique. By defining two subcutaneous anatomical triangles that can be safely lifted without disrupting the latissimus dorsi and serratus anterior muscles’ blood supply, this novel approach provides good exposure, preserves muscle flaps for future use, and minimizes dead space. As a result, this novel muscle-sparing thoracotomy technique has the potential to minimize postoperative complications and maximize patient outcomes.
